The "Quishing" Epidemic: Don't Scan That Code

Paramedic's Log:

We are seeing a new strain of infection spreading through the city. Unlike traditional viruses that come from clicking links, this one enters through the camera lens. We call it "Quishing" (QR Phishing).

1. Symptoms of the Attack

Criminals are physically pasting fake QR codes over legitimate ones on parking meters, restaurant menus, and electric scooter rentals. When scanned, the user is redirected to a clone site that steals credit card information instantly.

Digital Triage: Victims often realize the theft only when unauthorized charges appear days later. This is a "silent bleed" attack.

2. Why Anti-Virus Misses It

Most security software scans text and links, but they cannot "read" an image of a QR code effectively. This allows the malicious payload to bypass traditional firewalls and land directly on your mobile device.

3. Prevention Protocol (The Vaccine)

Before you scan, perform this 3-step check:

• Inspect physically: Is the QR code a sticker pasted over another sign? If so, do not scan.
• Check the URL: When your phone reads the code, does the preview URL look strange or shortened (e.g., bit.ly)?
• Avoid "Urgent" QR Codes: Be suspicious of emails containing only a QR code demanding immediate action.

Stay vigilant. The ambulance is always on standby, but your awareness is the first line of defense.
